Easily integrating bioinformatics web services

jORCA is a desktop client able to efficiently integrate different type of web-services repositories mapping metadata over a general definition to support scalable service discovery and to achieve flexible inter-communication between tools.
jORCA manages repositories heterogeneity supported by the Modular-API that provides a uniform view of metadata (e.g. GRID-based, WSDL–services, BioMoby and others), making the integration of bioinformatics Web-Services easier.


This software is intended to facilitate the use of Web-Services offering a friendly tool able to execute and integrate web-services that use different protocols.


This work has been performed and financed in the context of INB developments (National Institute for Bioinformatics, a platform of Genoma-España), and it is also being used in the framework of the Advancing Clinic-Genomic Trials’ EU-project (ACGT; Contract Code 026996).
Several partners helped us to improve the software. We thank very much all those partners, specially all the people acting as tool tester and all the bitlab ( team.

Note: the application requires java 6 or later .

jORCA has been tested under UNIX (Fedora 11, open SUSE 11 and Ubuntu 8.1), MS-Windows and Mac OS 10.5 operating systems. Java VM version 1.6 o later is required.
